Operating Modes - Bosch GRL4000-90CHVG Instrucciones De Funcionamiento Y Seguridad

Alternatively, you can switch on sleep mode
by pressing the sleep mode button (28) on
the remote control or with the leveling remote
app.
Do not switch off sleep
mode remotely without
line of sight to the laser tool. The sudden
bright laser beam may increase the risk of per-
sonal injury or property damage.
Ensure there are no bystanders in the direct
path of the laser beam before turning off
sleep mode remotely.
When sleep mode is switched on,
the sleep mode symbol will be indi-
cated on the display. The status in-
dicator (12) will slowly flash green.
The shock-warning function will remain acti-
vated and all settings will be saved.
To switch off sleep mode, briefly press the
on/off button (11) on the laser level or press
the button for sleep mode (28) on the remote
control.
You can also switch off the laser level while it
is in sleep mode by pressing and holding the
on/off button (11) until the switch-off symbol
appears on the display. All other buttons on
the laser level and the remote control will be
deactivated.
It is also possible to switch sleep mode on
and off via the Bosch Leveling Remote App.
Locking the keyboard
The keyboard of the laser level
and the remote control can be
locked via the Bosch Leveling Re-
mote App. The keyboard lock in-
dicator will appear on the laser level's display.
The keyboard can be unlocked as follows:
– via the Bosch Leveling Remote App,
– by switching the laser level on and off via
the on/off button (11)
– or by pressing the ▲/ (4) and ▼/ (3) but-

Operating Modes

Alignment of X and Y-axis
- Y
- X
(16)
The alignment of the X and Y axes is marked
on the housing above the rotation head. The
markings are exactly above the alignment
notches (16) at the bottom edge of the hous-
ing and on the lower handle. The laser level
can be aligned along the axes by using the
alignment notches.
Operating modes overview
All three operating modes are possible with
the laser level in horizontal and vertical posi-
tion.
Rotational operation
Rotational operation is espe-
cially recommended when us-
ing the laser receiver. It is possi-
ble to select between different
rotational speeds.
Line operation
In this operating mode, the vari-
able laser beam moves within a
defined aperture angle. This
increases the visibility of the
laser beam in comparison to
rotational operation. You can
select between different aper-
ture angles.
Point operation
In this operating mode, the
best visibility of the variable
laser beam can be reached.
For example, it is used to eas-
ily project heights or to check
building lines.
Line and point operation are not suitable for
use with the laser receiver (42).
